feature request: use builtin toolchains without upstream .pre-commit-hooks.yaml

[jmelahman]

I would like a way to automate the hook bootstrapping without needing to upstream a .pre-commit-hooks.yaml. Most maintainers rightful don't want a .pre-commit-hooks.yaml in their repo just to define the entry-point for a tool they're unfamiliar with. Conversely, I don't want to hassle with installation or compatibility issues while managing locally installed tools.

Effectively the equivalent of,

repos:
  - repo: local
    hooks:
      - id: go-build-and-run
        language: system
        entry: bash -c 'set -euo pipefail; go build github.com/me/my-app@v1.0.0 -o /tmp/my-app && /tmp/my-app'

But using the builtin go toolchain + pin a revision to ensure compatibility across users.
Something along the lines of,

repos:
  - repo: github.com/me/my-app
    rev: v1.0.0
    hooks:
      - id: go-build-and-run
        name: My app
        language: golang
        entry: my-app

Also, I think this would improve existing pre-commit providers. Cases like uv-pre-commit where the tool version is frozen in the repository. This allows those tools to be kept fresh with prek auto-update (rather than keeping the hook implementation fresh and maybe implicitly the tool). These provider repos (like uv-pre-commit) may even become mostly obsolete?
